Main Ingredients (3-Ingredient Base)

That’s it.

Optional Flavor Boosters (Highly Recommended!)

• Pinch of sea salt
• ¼ teaspoon baking soda (for slight lift)
• 2 tablespoons sugar-free chocolate chips

How to Make Flourless Cookies with Zero Sugar

PIN IT

Step 1: Preheat the Oven

Preheat to 350°F (175°C) and line your baking sheet with parchment paper.

Step 2: Mix the Dough

In a bowl, combine:

• Peanut butter
• Egg
• Sugar-free sweetener

Mix until smooth and fully incorporated. The dough will be thick and glossy.

If adding vanilla, baking soda, or salt — mix them in now.

Step 3: Shape the Cookies

Scoop tablespoon-sized balls onto the baking sheet.

Use a fork to gently press down, creating that classic crisscross pattern. This not only looks beautiful — it helps them bake evenly.

Step 4: Bake

Bake for 8–10 minutes.

The cookies may look slightly underdone in the center when removed. That’s perfect. They firm up as they cool.

Step 5: Cool

Let them rest on the baking sheet for 5 minutes before transferring.

Resist the urge to move them too soon — they’re delicate when hot.

What to Serve with These Cookies

These cookies shine alongside:

• Black coffee
• Cappuccino
• Almond milk latte
• Herbal tea
• Sugar-free vanilla ice cream

They also crumble beautifully over yogurt bowls.

Tips for Perfect Flourless Cookies

• Do not overbake — that’s the secret to softness.
• If dough feels too oily, chill for 10 minutes.
• For crispier cookies, bake 1–2 minutes longer.
• For softer cookies, remove at 8 minutes exactly.

Store in an airtight container up to 5 days.
